  Null hypothesis Vs. Alternative hypothesis A hypothesis is a claim or statement about a population parameter. Usually, the results of a sample are applied to generalize on an entire population(s). For example, in a class of 30 students, 12 students are sampled for their test scores. The result is that the average score is 83. This result would, however, vary with another sample. A hypothesis can be a null hypothesis or an alternative hypothesis. A null hypothesis is a statement what the majority holds to be true. The opposite or complement of a null hypothesis is an alternative hypothesis. Let us understand a problem: A light bulb manufacturer claims that the average life of their light bulb is 1000 hours. A worker believes it is not 1000 hours. He tests the claim by taking a sample of 500 bulbs. A null hypothesis (Ho) is an accepted truth and assumes that the alternative claim is false. An alternative hypothesis(H1) is what the researcher is trying to prove. In this problem, the...

Name: Elephant in the store room Author: Dr. Anu Teotia The Elephant in the store room by Dr. Anu Teotia is a self help book to forgive things, move on and lead a positive life ahead. The cover page of the book is neat, elegant and pleasant. The title of the book was pretty intriguing to pick up this book. Its justification goes like this. Everyone will not talk about their worst negative events in their life as it will be too painful for them and they shift those events thought to a store room in their mind wherein it is stored in their unconscious mind and takes control over their life without even realising it. Hence, the author says that the elephant must be taken out of the store room in your unconscious mind. It was a unique and creative example to make readers understand the content. Every chapter is maximum two pages length backed with daily activities and meditation exercises to help you achieve it in a more effective way. The language is simple and I recommend to all who want...

  “Talking about the problems of the world without talking about some accessible solutions is the way to paralysis rather than progress.” 🖤 BOOK : POOR ECONOMICS  AUTHORS : @abhijit_banerjee._ & @esther.duflo_official 🖤 This book  discusses the general perspective of below poverty and the economic policies to alleviate poverty and to rise them to a cycle of wealth and prosperity.  🖤 It's surely a helping hand for developing countries and countries who are at their hard times. 🖤 When I read this book, I personally think it's too relatable to my country India where poverty and unemployment are in large numbers.  If India follows their techniques to address the twin problems, the result would be more effective. 🖤 It's not a 'economics only' book.

If you're new to economics,  I am pretty sure it would change ...
